I have those options checked, but I need to enable "Check for server certifcate revocation"?? I don't understand why I would need to click on that to hit an HTTPS site? This is with Windows NT4.0 and NT4.0 server as well???

If using dial-up networking, one might delete the wsock2 keys in the registry and then remove and re-install dialup networking. This corrected a problem with a client machine using Win98 when the suggestions you present here didnot work.

Thank you, Thank you, Thank you!!!! I have been unable to browse to any secure site using IE6/XP home for some time. I had read (nearly) everything I could find online about this problem and tried every suggestion. Your suggestion to check the proxy settings was correct. I think the settings were left over from an installation of Winproxy that has been unistalled. Thanks again.
